CHÉOS Scientists front and centre at ISOQOL 2017

Posted on


The 24th Annual Conference of the International Society for Quality of Life Research (ISOQOL) takes place  between October 18 and 21 in Philadelphia. The conference, entitled Embracing Complexity: Using Patient-Reported Outcomes to Generate Real World Evidence, features presentations and seminars from researchers from around the world, including CHÉOS Scientists.

Dr. Skye Barbic, who will receive the 2017 Emerging Leader Award at the conference, is presenting her work in both poster and oral format and is co-author on two other presentations. Dr. Rick Sawatzky will be giving both an oral and poster presentation, his postdoctoral fellow Lara Russell will be delivering two oral presentations, and both are co-authors on another oral presentation.

Both Dr. Barbic and Sawatzky serve on the Education Committee for ISOQOL and Dr. Sawatzky was an abstract reviewer for this year’s conference. Two other CHÉOS Scientist, Drs. Steve Mathias and Anne Gadermann, are co-authors on one presentation each.
ISOQL 2017 “will provide a platform to discuss the challenges for the field with regards to theory, methodology, and implementation of results in health care policy and practice”. For a full list of conference proceeding please see the ISOQOL 2017 Program.
